Sorting on notice.id when our primary selector was notice_inbox.user_id caused a filesort and table scan of the notice table.
Switchng to notice_inbox's notice_id means we can use our index, and everything comes right up.
Before:
mysql> explain SELECT notice.id AS id FROM notice JOIN notice_inbox ON notice.id = notice_inbox.notice_id WHERE notice_inbox.user_id = 18574 AND notice.repeat_of IS NULL ORDER BY notice.id DESC LIMIT 61 OFFSET 0;
+----+-------------+--------------+--------+------------------------------------+---------+---------+-------------------------------+--------+----------------------------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+--------------+--------+------------------------------------+---------+---------+-------------------------------+--------+----------------------------------------------+
| 1 | SIMPLE | notice_inbox | ref | PRIMARY,notice_inbox_notice_id_idx | PRIMARY | 4 | const | 102600 | Using index; Using temporary; Using filesort |
| 1 | SIMPLE | notice | eq_ref | PRIMARY | PRIMARY | 4 | stoica.notice_inbox.notice_id | 1 | Using index |
+----+-------------+--------------+--------+------------------------------------+---------+---------+-------------------------------+--------+----------------------------------------------+
After:
mysql> explain SELECT notice.id AS id FROM notice JOIN notice_inbox ON notice.id = notice_inbox.notice_id WHERE notice_inbox.user_id = 18574 AND notice.repeat_of IS NULL ORDER BY notice_id DESC LIMIT 61 OFFSET 0;

self-subscription) via the API. Additionally, make it impossible
to block yourself or unsubscribe from yourself, period.
I also made User use the subs.php helper function for unsubscribing
during a block.
Hopefully, these changes will get rid of the problem of people
accidentally deleting their self-subscriptions once and for all
(knock on wood).
Added a right for new notices, realized that the hasRight() method
should be on the profile, and moved it.
Makes this a less atomic commit but that's the way it goes sometimes.
Added EmailAuthenticationPlugin
Added ReverseUsernameAuthenticationPlugin
Changed the StartChangePassword and EndChangePassword events to take a user, instead of a nickname
User::allowed_nickname was declared non-static, but used as if it was static, so I made the declaration static
The User_openid data object was explicitly listed as a related field to delete from in User::delete(); this class doesn't exist anymore by default since OpenID was broken out to a plugin.
Added UserDeleteRelated event for plugins to add related tables to delete from at user delete time.
This reverts commit 15f9c80c28.
So, so, elegant! And so, so, incorrect!
We can't have a user named 'notice' because that would interfere with
URLs like /notice/1234. However, there is no file named 'notice' in
the Web root.
If there were a way to automatically pull out the virtual paths in the
root dir, this may make sense. Until then, we keep track here.
Added a local directory for locally-installed software. This is where
you should put any code you write, themes, plugins, etc. so they don't
get stomped by upgrades.
"Rememberme" logins aren't allowed to make changes to an account
(since cookie-stealing is too easy). Users have to re-authenticate.
Previously, it was impossible to do so without having a username and
password; this change lets you do it with OpenID, too.
More PEAR coding standards global changes. Here, I've changed all
instances of TRUE to true and FALSE to false.

Another huge change, for PEAR code standards compliance. Function
headers have to be in K&R style (opening brace on its own line),
instead of having the opening brace on the same line as the function
and parameters. So, a little perl magic found all the function
definitions and move the opening brace to the next line (properly
indented... usually).

Another global search-and-replace update. Here, I've replaced the PHP
keyword 'NULL' with its lowercase version. This is another PEAR code
standards change.

The PEAR coding standards decree: no tabs, but indent by four spaces.
I've done a global search-and-replace on all tabs, replacing them by
four spaces. This is a huge change, but it will go a long way to
getting us towards phpcs-compliance. And that means better code
readability, and that means more participation.

I moved the 4 streams for a user (with friends, faves, replies,
personal) into functions on the User object. Added a helper function
in Notice for making notice streams. Also, will fetch notice streams
out of the memcached server, if possible. Made the API, RSS, and HTML
output all use the same streams (hopefully cached).
Added some code to Notice to blow the cache when a notice is posted.
Also, added code to favor and disfavor actions to blow the faves
cache, too.

I added a new class, Memcached_DataObject, that will (optionally)
fetch data out of a memcached server if it's available. This only
works on 'staticGet'.
Methods that write to the database (insert, update, delete) will clear
and set the cache correctly, too.

Add the code to registration to handle invitation codes.
Some edge cases on invitations: is the user already subbed to this
person? Tell them. Is the person already on the system? Sub the user
to them, then, and tell the user.
Add some code to User to auto-sub invitees whenever the email address
changes. Call it from a new registration with an invite code, and also
from confirmaddress.
Some whitespace cleanup in the files touched.

noticesWithFriends is turning out to be one of our most expensive
queries. The join is costly, and this method is hit over and over and
over by desktop clients and other API users.
So, I've added a first pass at caching the results. I store a "window"
of notices -- equal to the first 3 pages of notices, plus one for
pagination -- in the memcached cache. If with-friends notices are
requests, I fetch the whole window out of the cache and grab the slice
requested. If the requested notices are outside the window, we just do
the query. If there's nothing in the cache, we request the window and
store it, then return a slice.
I had to add a NoticeWrapper class that works like DB_DataObject
(well, just the fetch() part...) but just holds an array of notices
instead of a DB cursor.
Finally, saving a new notice blows away the caches for subscribed users.
